Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An electronic device comprising: a memory storing computer-readable instructions for causing the electronic device to implement a method of transferring a secure rights object (RO) between the electronic device and an external device; and a processor which when executing the computer-readable instructions is configured to control the electronic device to implement the method of transferring the secure RO between the electronic device and the external device, the method comprising: interfacing, by the electronic device, with the external device that transmits a copy of the secure RO; receiving, by the electronic device, the copy of the secure RO from the external device in a first transmission from the external device; notifying, by the electronic device, the external device that the receiving of the copy of the secure RO has been completed, wherein the external device removes the secure RO from a memory within the external device in response to the notifying; receiving, by the electronic device, a request for decryption of the copy of the secure RO from the external device in a second transmission separate from the first transmission, wherein the request for decryption includes an encryption key used by the external device to generate the secure RO; in response to the request for decryption of the secure RO, decrypting, by the electronic device, the secure RO using the encryption key; and notifying the external device that the decrypting of the secure RO has been completed.
An electronic device transfers a secure rights object (RO) with an external device. The device interfaces with the external device to receive a copy of the secure RO in a first transmission. After receiving the RO, the device notifies the external device, prompting the external device to remove the RO from its memory. The device then receives a decryption request in a second, separate transmission, including the encryption key used to generate the secure RO. Upon receiving the request, the device decrypts the RO using the provided key and notifies the external device of completion.
2. The electronic device of claim 1 , wherein the processor when executing the computer-readable instructions is further configured to store the secure RO received from the external device in the memory.
The electronic device described in the previous claim also stores the received secure RO in its memory. The device interfaces with an external device to receive a copy of the secure RO in a first transmission. After receiving the RO, the device notifies the external device, prompting the external device to remove the RO from its memory. The device then receives a decryption request in a second, separate transmission, including the encryption key used to generate the secure RO. Upon receiving the request, the device decrypts the RO using the provided key and notifies the external device of completion. The secure RO is stored for later use or processing.
3. The electronic device of claim 2 , wherein the secure RO has an identification module by which the secure RO to be distinguished from a RO which is not encrypted.
The electronic device described in claim 2 stores the received secure RO in its memory and the secure RO incorporates an identification module. This module enables distinguishing the encrypted RO from a standard, non-encrypted RO. This identification ensures that the device can differentiate between secure and regular ROs for appropriate processing and handling, maintaining security protocols. The device interfaces with an external device to receive a copy of the secure RO in a first transmission. After receiving the RO, the device notifies the external device, prompting the external device to remove the RO from its memory. The device then receives a decryption request in a second, separate transmission, including the encryption key used to generate the secure RO. Upon receiving the request, the device decrypts the RO using the provided key and notifies the external device of completion.
4. The electronic device of claim 2 , wherein the processor when executing the computer-readable instructions is further configured to distinguish the secure RO from a RO which is not encrypted.
The electronic device from claim 2, which stores the received secure RO in memory, is configured to differentiate the secure RO from a standard, non-encrypted RO. Instead of relying on an embedded identification module, the device itself possesses the logic or method to distinguish between secure and regular ROs. This might involve checking for specific encryption headers or metadata, or using cryptographic checks to verify the RO's integrity. The device interfaces with an external device to receive a copy of the secure RO in a first transmission. After receiving the RO, the device notifies the external device, prompting the external device to remove the RO from its memory. The device then receives a decryption request in a second, separate transmission, including the encryption key used to generate the secure RO. Upon receiving the request, the device decrypts the RO using the provided key and notifies the external device of completion.
5. A method of transferring a secure rights object (RO) between an electronic device and an external device, the method comprising: interfacing, by the electronic device, with the external device that transmits a copy of the secure RO; receiving, by the electronic device, the copy of the secure RO from the external device in a first transmission from the external device; notifying, by the electronic device, the external device that the receiving of the copy of the secure RO has been completed, wherein the external device removes the secure RO from a memory within the external device in response to the notifying; receiving, by the electronic device, a request for decryption of the copy of the secure RO from the external device in a second transmission separate from the first transmission, wherein the request for decryption includes an encryption key used by the external device to generate the secure RO; in response to the request for decryption of the secure RO, decrypting, by the electronic device, the secure RO using the encryption key; and notifying the external device that the decrypting of the secure RO has been completed.
A method for transferring a secure rights object (RO) between an electronic device and an external device involves several steps. First, the electronic device interfaces with the external device. The electronic device then receives a copy of the secure RO from the external device in a first transmission. Upon successful receipt, the electronic device notifies the external device, which triggers the external device to remove the secure RO from its own memory. Following this, the electronic device receives a request to decrypt the RO from the external device in a second transmission, separate from the first. This request includes the encryption key used to create the secure RO. In response, the electronic device decrypts the RO using the provided key. Finally, the electronic device notifies the external device that the decryption process is complete.
